Life cycle of the dimorphic sugarcane smut fungi, Sporisorium scitamineum, involves recognition and mating of compatible saprophytic yeast-like haploid sporidia (MAT-1 and MAT-2) that upon fusion, develop into infective dikaryotic mycelia. Although the dimorphic transition is intrinsically linked with the pathogenicity and virulence of S. scitamineum, it has never been studied using a proteomic approach.

At present, the most practical and effective management strategy for the disease is the cultivation of resistant cultivars. In this connection, a detailed understanding of the host's defense mechanism in response to smut isolates with varying degrees of virulence at the molecular level would facilitate the development of reliable and durable smut-resistant sugarcane varieties.

With the accumulating information on pathogenicity determinants, namely, effectors and pathogen-associated molecular patterns (PAMPs) of C. falcatum, it is of paramount importance to decipher the functional role of these molecular players that may ultimately decide upon the outcome of sugarcane-C.

Considering the significance of deciphering its secretome, we have examined alterations in the in vitro secretome of S. scitamineum in response to synthetic and sugarcane meristem tissue-amended growth media, so as to identify host signal responsive secretory proteins.

Unlike other comparable monocots like sorghum, maize, and rice, sugarcane genome by virtue of its polyploidy nature remains yet to be fully deciphered. Proteomics-an established complementary tool to genomics is at its infancy in sugarcane as compared to the other monocots.
View Article and Find Full Text PDFRed rot disease of sugarcane caused by Colletotrichum falcatum is one of the serious constraints affecting the productivity of the crop. The strategy of employing systemic acquired resistance (SAR) against red rot yielded consistently good results at field level. However, elucidation of genes involved in the induction of SAR continues to be a challenging area of research for a critical understanding of red rot disease resistance in sugarcane.

Plant proteomics has made tremendous contributions in understanding the complex processes of plant biology. Here, its current status in India and Nepal is discussed. Gel-based proteomics is predominantly utilized on crops and non-crops to analyze majorly abiotic (49 %) and biotic (18 %) stress, development (11 %) and post-translational modifications (7 %).
View Article and Find Full Text PDFSugarcane is an important commercial crop cultivated for its stalks and sugar is a prized commodity essential in human nutrition. Proteomics of sugarcane is in its infancy, especially when dealing with the stalk tissues, where there is no study to date. A systematic proteome analysis of stalk tissue yet remains to be investigated in sugarcane, wherein the stalk tissue is well known for its rigidity, fibrous nature, and the presence of oxidative enzymes, phenolic compounds and extreme levels of carbohydrates, thus making the protein extraction complicated.
